To all whom it may concern:

Be it known that l, Jnnoiun lL. TINDALL, a citizen of the United States, residing at 307 West Fifteenth Street, in the city of Pueblo, county of Pueblo, and State of Colorado. have invented a new and useful lVater-Tube Steam Producer, of Which the following is a specification.

My invention relates to improvements in water tube steam producers in which there are three major sections situate with relation to one another so that there is a saving of the heat and a complete and efiicient circulation is provided in all the Water tubes of the system. The water enters these sections through the economizer section and then to the steam producer section and thence to the superheating section.

My objects in this form of water tube steam producer are, first, to arrange the pas" sages for the water through the tubes oil the steam producer in such a Way that the circulation will be entirely free and unhampered; second, that the heating surface be so arranged that the heat will be absorbed to the minimum of loss; third, that a minimum oi space and weight be required for the steam producer; fourth, to produce a steam producer that may be more cheaply constructed and with superior efliciency; fifth, to provide means for removing salts and sediment from the Water in the Water tubes of the steam producer. I attain these objects by means of the water tube appliances illustrated in the accompanying drawin s, in Which igure 1, is a plan view of the water tube steam producer, not showing the housing or jacket or the burner; Fig. 2, is a vertical sectional View of the Water tube steam producer on the line 22 in Fig. 1; and Fig. 3, is an elevation looking at the right side of Fig. 1.

Similar letters and similar numerals refer to similar parts throughout the several Views.

'llhe economizer section A consists of a system of small Water tubes bent to conform to arectangular space near the line or vent for the hot gases and is so placed and proyided as to absorb the remaining heat from the escaping Warm gases. This system of tubes are Welded together in one continuous line of tubing. The feed Water is delivered to the economizer section from the feed Water pumps through the tube. 1, and alter passing through the economizer system is delivered through the tube 2, to the steam generating section B. This tube 2, passes longitudinally through the large cylinder E, and is closed at its extreme end. Within the cylinder E, the tube 2 has a multiplicity of outlets 3, 3, which open into the ends of the downward-extending tubes 4:, 42, which pass horizontally under the rest of the pipes of the steam generating section B, and empty into the common header pipe or distributor This distributor 5 is provided at each end with flanged caps 6, removably attached to enable one to clean out the dcposited salts and debris that may be precipitated from the heated Water. From the distributor 5 the water gradually rises by passing forth and back through the gradually inclined tubes 7, 7, of the steam generating section B, and enters the steam-andwater separating cylinders D and E. The deflector plates 8 and 9, in the cylinder D, and the deflector plate 11 acting with the projecting side of the tube 2, in cylinder E, tend to direct the Water across their respective cylinders and cause it, when relieved of its steam which escapes up between said deflectors. to descend again downwardly through the tubes 4c, 4, to the distributor.

The water level is maintained in the Water tube steam producer at a point near the dotted line 14, and a little above the deflector plates 8, 9, and 11, and above the cross tubes 10.

it is plain, that when the steam escapes between the deflector plates 8, 9, it will leave the Water from which it escapes lighter than when it was charged with hot steam, and inclined to pass downwardly and horizontally through the cross tubes 10 to the separating cylinder E, where it is relieved of the rest of its steam, and then has a tend- Bil till

ency to being forced downwardly in the ldtl tlue. llhc bafile 20, protects the feed water in the tubes 4 from being excessively heated so that its specific gravit will be enough greater than the waters in the tubes 7 to maintain the normal and uninterrupted circulation therein.

The tube 15 has its upper end tightly inserted into the end of tie steam reserve cylinder 1F and'that part within F, has numerous perforations permitting the steam to enter it to escape into the numerous and continuous tubes of the superheater section C. Tube 15 extends downwardly and conveys the wet steam from the reserve cylinder F to the superheater section G where it enters at the point 16, and after passing back and forth through the continuous line of tubes of the superheater section C, passes out at the point 17 of the tube 18 on its way to the eng ne.

Una of the purposes in having the superheater section away from the hottest gases of the furnace is to prevent its pipes from getting suddenly too hot, as the superheated ry steam will not readil protect the pipes as water or wet steam will I am aware that prior to this invention water tube steam producers have been invented and used, and therefore ll do not claim broadly the system of water tube steam boilers, but, ll claim-- 1. A water tube steam-producing appliance of the class described, comprising in combination, three tubular sections, the first section disposed at the Outlet of the furnace gases, and provided to absorb the remaining cat by contact of the gases with the numerous small horizontal tubes containing the cool water from the supply pipe, the second section comprisin numerous horizontally disposed pipes in tiers and provided to generate the steam by contact with the hottest gases of the furnace, two large horizontally-disposed cylinders situate above said second section and extending parallel with the tubes of the first'section, which is over one end of the second section, one of said cylinders being over the opposite end of the second section from the first section and the other located near the first section, the space between said cylinders being the passage for the hot gases from the second section to the other sections, a bafile shield extending horizontally under the first section and over the end of the second section and into contact with the side of the nearest cylinder provided to conduct the hot gases from the second section u between said cylinders, and an upright afile shield extending downwardly from the under side of the other cylinder.

2. In a water tube steam producer of the class described, having three distinct sections in the system, comprising an economizing section at the water supply end of the connected series and a steam generating eccneiaeoc tion situate at the under side of the system, and a superheating section above the second section, the combination in the superheating section of an end cylinder, a central cylin: der, and an upper cylinder, a bafile shield extending downwardly from the said end cylinder provided to conduct the hot gases up between the end cylinder and the central cylinder, a battle shield extending horizontally from the central cylinder between the first section and the second section provided to conduct the hot gases from the second section up between said end cylinder and said central cylinder to the superheating section and said upper cylinder, connecting tubes provided to conduct the water from the side of the central cylinder to the lower side of the end cylinder, downwardly extending tubes having their intake in the side of said end cylinder, a header pipe at the bottom of the second section in the line of the water circulation between said downwardly extending tubesprovided for distributing the water received therefrom to the steam generating section, and deflector plates in said end cylinder, just below the water surface in the superheating section, provided for the escape of the steam and for the deflecting of the water back into the circulation of the said second section.
